 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Orientable Surface Type</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * OrientableSurface consists of a surface and an orientation. If the orientation is "+", then the OrientableSurface is identical to the baseSurface. If the orientation is "-", then the OrientableSurface is a reference to a Surface with an up-normal that reverses the direction for this OrientableSurface, the sense of "the top of the surface".
